(d) The risk of breakdown due to the gearing connecting the engines with the propeller shaft is likely to be remote.

(e) The complete power unit is self-contained, and is convenient for mounting in an aeroplane. The position for the auxiliary units, carburetors, magnetos, exhaust pipes, etc., is convenient and the whole unit lends itself to the design of a low resistant aeroplane.

(f) The power unit consists of three separate engines. When getting off the ground all throttles can be opened wide and the engines will run at their full normal revolutions. When flying level at cruising speed the throttles will be shut until the same revolutions are obtained. Should one engine break down then if the throttles of the remaining two are opened wide, the full horse power of each engine will be available. By this means it will be possible to carry on at normal cruising speed with one engine completely broken down.
